Application filed November 12,1917. Serial. No. 201,491.

To all whom it mayconcem:

Be it known that 1, JOHN B. HADAWAY, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain new and usefullmprovements in Channel-Closing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for operating upon soles and more particularly to machines of thistype which are employed for closing the channel of a sole'to which the upper of a boot or shoe has been secured.

The soles of both welt and turn shoes are frequently provided with a channel for the reception of the stitches which connect the sole and upper together and it is desirable, especially in the case of turn shoes, toclose this channel after the upper has been permanently connected to the sole.

Accordingly, an object of the present invention is to provide a machine of simple and compact construction which shalleflectually lay the channel flap or lip of the sole after the upper has been connected to the sole by a permanent seam.

With this object in view, then, a feature of the invention contemplates the provision of a tool provided with a working end adapted to project" beneath the margin of the upper and bear upon the upstanding lip of a sole, together with means for imparting a reciprocatory movement to the tool to pound the lip into the channel.

Another feature of the invention comprises a channel-closing tool constructed and arranged to bear directly upon the channel flap and project between the channel flap and the projecting edge of the upper con nected thereto and mechanism for imparting a short vibratory movement to the tool to pound the lip into the the channel without displacing the projecting end of the tool from between the lip and the edge of the upper.

Still further features of the invention consist in certain novel features of construc- .anism for vi tion, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the accompanying'description.

In the accompanying drawings, Figure 1 represents a side elevation of the improved machine, partly in section, with the shoe shown in the proper relation thereto; and Fig. 2 is a front elevation of the tool and operating mechanism.

In the manufacture of turn shoes to which the illustrated embodiment of the present machine is particularly adaptpd the seam connecting the upper to the sole is received in a channel formed in the surface of the sole, and prior to the turning of the shoe it is essential that the upstanding lip or flap shall be forced into place to close the channel and completely cover the stitches prior to the trimming of theup er and subsequent operations upon ,the shoe. This closing vof the channel is best accomplished by hammering down the lip through a tool which engages directly therewith and moves in a path substantially normal to the plane of the sole. Accordingly, the present invention comprises a channel closing tool which extends transversely of the upstanding lip and projects between the lip and the projectin edge of the upper, and mechbratlng the tool to pound the lip into place in the channel. During the feeding movement of the shoe relative to the tool the end of the tool acts as a plow to separate the upper and the lip of the sole, the short vibratory movement imparted to the tool being insufficient to displace the tool from its position between the lip and the projecting edge of the upper.

In the illustrated embodiment of the invention the head of the machine is indicated at 10 and is provided with a shaft 11 journaled therein, which carries a series of concentrically arranged rolls 12 upon its outer end. These rolls, as shown clearly in Fig. 1, are loosely journaled between the hubs 13 and 14 secured to the end of the shaft 11. The channel closing tool is indicated at 15 and is provided with a shank 16 slidingly supported in a casing 17 secured to the face of the head 10 through bolts 18. As shown clearly in the drawings the sliding movement of the tool relative to the casing 17 is limited by the engagement of a pair of lugs 20 and 21 with the head 22 of a stop screw 23 threaded in the lower portion of the easing 17. With this construction when an upward pressure is exerted upon the tool 15 to move the upper end of the tool into engagement With the rolls 12, a rapid vibration is imparted to the tool by the successive engagement of the rolls therewith.

The tool is designed to project transversely across the lip of the sole and is provided with a wedge-shaped end 24: which is adapted to project beneath the edge of the upper and separate the upper from the adjacent lip. The opposite sides of the tool, as shown in the drawings, are relieved so that the latter forms in effect a plow which serves to separate the projecting edge of the upper and the lip during the feeding movement of the shoe. l/Vith this construction the shoe is placed in position with the upstanding lip engaged by the lower face of the channel closing tool and is then pressed upwardly to cause the tool to be vibrated by the rolls 12, this vibratory movement serving effectually to force the lip into place and close the channel. The force of the blows delivered by the tool is dependent upon the upward pressure exerted upon the tool and accordingly the operator, by a proper manipulation of the shoe, may vary the pounding action upon the lip as desired.

While it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential except so far as specified in the claims, and may be changed or modified without departing from the broader features of the invention.

2. A channel closing machine having in.

combination, a tool constructed and arranged to bear directly upon the lip of the sole and project between the lip and the projecting edge of the upper connected thereto, and means for imparting a short vibratory movement to the tool to pound the lip into the channel without displacing the projecting end of the tool from between the lip and the edge of the upper.

3. A channel closing machine having, in combination, a rotary shaft,a closing tool h(ving a vertically disposed shank and a wedge-shaped end which is adapted to eX- tend transversely across the lip of the sole and project beneath the edge of the upper to separate the upper from the adjacent lip,

and connections between the rotary shaft and the shank of the tool to impart a short vibratory movement to the tool in a vertical direction and pound the lip without displacing the tool from its position beneath the margin of the upper.

at. A channel closing machine comprising a head, a tool having a shank slidingly supported in the head, means for reciprocating the tool in the head, a pair of lugs projecting from the side of the shank, and a stop screw threaded in the head parallel to the direction of movement of the tool and engaging with the lugs to vary the limit of movement of the tool. 1
